地震发生时在室内的人千万不要仓惶出逃。原因之一是来不及跑,地震持续的时间很短,尤其是在楼房、大车间里的人更来不及跑。原因之二是跑不动,若 6级地震,地震烈度可达 8度,相当于人在汽车中受猛开猛刹的撞击,无法把握重心,想跑也是力不从心,原因之三是仓惶出逃危险性大,地震时大家都涌在门口楼梯上,在短暂的几妙钟时间里不但撤不出去,还容易摔伤跌伤;由于地震时门窗变形,支撑力弱,这时拉门挤门,危险性很大。有的人来不及跑就跳楼,危险性就更大。地震发生时,正确的应急避险方法是在室内的人立即找安全空间就近躲避,震后迅速撤离,防止余震袭击;在室外的人要等地震波过去后,再进室内救人取物。 People who are indoors indoors during an earthquake must not flee. One of the reasons is that it is too late to run, and the duration of the earthquake is very short, especially when people in buildings and large workshops are too late to run. The second reason is that it cannot run. If a 6-magnitude earthquake has an earthquake intensity of 8 degrees, it is equivalent to the impact of a fierce brake in a car. It is impossible to grasp the center of gravity, and it is also impossible to run. The third reason is to escape. The danger was high. Everyone rushed to the stairs at the time of the earthquake. Not only couldn’t they withdraw in a short time, but it was also easy to fall and fall; due to the deformation of the doors and windows during the earthquake, the supporting force was weak. At this time, the sliding doors crowded the door. There is a lot of danger. Some people jumped to the building before they could run. The danger was even greater. When an earthquake occurs, the correct method of emergency avoidance is for people in the room to immediately seek a safe space to evade. After the earthquake, they are quickly evacuated to prevent aftershocks from being attacked. People outside the home must wait for the earthquake wave to pass and then enter the room to save people.
